Tierrasanta man arrested in Jamul arson-murder

EAST COUNTY  A second San Diego man suspected in a September arson-murder in Jamul was arrested Thursday at his Tierrasanta home, a sheriff’s homicide official said.

Investigators took Devin F. Gaillard, 21, into custody at his apartment on Pendiente Court about 1 p.m., authorities said.

On Jan. 25, Miles B. Sharp, 21, of Rancho Peñasquitos, was jailed in connection with the same case.

Both men are suspected of killing Dillon A. Davis, 20, putting his body in the trunk of his car and driving him to Jamul, then setting the car on fire on Sept. 20, homicide Lt. Glenn Giannantonio said.

A passerby saw the fire on Skyline Truck Trail and called 911. Firefighters found the body after extinguishing the blaze.

Giannantonio said the three men were acquaintances. He declined to give any information about how, where or why Dillon was killed. He said investigators have processed what they believe to be the scene of the slaying.
